Computer Audiophile, a site that focuses on desktop audio and music servers, has reviewed the HeadRoom Ultra Micro DAC ($699) and Ultra Micro Headphone amp ($699). Reviewer Chris Connaker praised the combination for its small size and good synergy, but had a couple of minor quibbles about the design.
The Ultra Micro components definitely don’t suffer any performance hits because of their size, but they do have some design compromises that should be considered before a purchasing decision is made.
